### 5/5 — Does the job really well

*2021-09-17, version 1.1.1*

Simple to use, self explanatory, effective

### 5/5 — App is awesome but..

*2019-01-10*

Love the app but how do you keep it open and not go into background mode. Toggled background off and it turns itself back on. I would like to keep the screen open to the timer.

### 5/5 — Gem!

*2017-09-02*

Truly megamazingsuperduperultratastic! Thank you for designing this app to be extremely user-friendly and without in-app purchasing... & FREE. <3

### 4/5 — Great timer - 1 improvement

*2017-07-21, version 1.1.1*

Love this timer for my HIIT workouts. The only improvement would be to play music through the app. I'd really like the ability to play my Spotify playlists. Only a small request but it would certainly make this the best timer available.

### 5/5 — Perfect.

*2017-07-11*

Does exactly what you need with no unnecessary frills. 

Especially important that it doesn't take over the sound, allowing music to keep playing while doing intervals.

### 5/5 — Simple, Intuitive, and Easy to Use

*2017-05-22*

Great app--it does exactly what it needs to. Thank you for keeping it free and free of in-app purchases.

### 5/5 — Free, simple to use and no in app purchase BS

*2017-05-10*

Apps are not easy to write, so thanks for donating your time to save us from in app purchase stupidity.

### 5/5 — Great Tabata timer

*2016-11-17*

Simple, minimalist design. Does exactly what I want for my interval training and Tabata training sessions. The best part, no annoying ads at all! Thank you.
